A vehicle crash cushion (10) is mounted to a wall (W) adjacent to a roadway (R). The cushion (10) includes an array of panels (12) positioned to overlap one another and oriented parallel to the wall (W). A mechanical linkage (16) couples the panels (12) to the wall (W) and suspends the panels (12) above grade such that the panels (12) are movable toward the wall (12). Energy absorbing elastomeric tubes (30) are positioned between the panels (12) and the wall (W) such that movement of the panels (12) toward the wall (W) deforms the energy absorbing elastomeric tubes (30), thereby retarding movement of the panels (12) toward the wall (W) .

Amortisseur d'impact de véhicule (10) fixé à un mur (W) près de la route (R). L'amortisseur (10) comprend un groupement de panneaux (12) disposés de manière à se chevaucher et parallèles au mur (W). Une liaison mécanique (16) raccorde les panneaux (12) au mur (W) et les suspend au-dessus du sol, de sorte qu'ils peuvent se déplacer vers le mur (12). Des tubes élastomériques amortisseurs (30), placés entre les panneaux (12) et le mur (W), se déforment lorsque les panneaux (12) se déplacent vers le mur (W), ce qui retarde par conséquent le déplacement des panneaux (12) en direction du mur (W).
